Summary

The Omano OM157B is for the more discerning microscopist with a desire for a higher quality image produced by semi-plan objectives. The microscope includes four semi-plan objectives and a full range of professional features to make for a high quality microscope with contemporary design. An added feature is an easily accessible lamp housing for convenient bulb changes.

Optics

With a Seidentopf microscope head inclined at a more comfortable 30 degree angle, the Omano OM157B-SP offers a combination of improved optics and more modern design over the Omano OM36 and OM88 series. Most important, are four semi-plan, parcentered, parfocal and fully coated objective lenses (4x, 10x, 40x spring, 100x spring oil immersion) that produce a better quality and flatter image than standard lenses.

WF10x/18mm eyepieces include eyecups for improved viewing while the head is easy to swivel through 360 degrees for flexible viewing positions or to share with a colleague. The head also includes interpupillary adjustment of 55-75mm in order to adapt to different viewer head sizes.

The quadruple nose piece is rear-facing to enable easier slide handling. Both the 40x and 100x objectives are spring-loaded to mitigate the risk of damage to the slide or objective. Magnification levels include 40x, 100x, 400x and 1,000x.

Stage & Focus

A large double-layered mechanical stage measures 140mm x132mm and includes spring-loaded slide clamp and dropdown coaxial controls for convenient 'eyes down' operation. The stage range of movement is 70mm x 30mm. Focusing includes high quality rack and pinion mechanics for longer life and coaxial coarse/fine focus controls for easier focusing.

The fine focus scale value is 0.002mm. Safety features include a rack stop to ensure that the stage does not impact with the objectives and thereby break the slides, and a slip clutch control to mitigate the risk of damaging the focus controls through over extension.

Condenser & Illumination

The condenser is a professional Abbe 1.25 N. A with iris diaphragm and filter for optimal adjustments. Transmitted illumination is 110V/220V 6V 20W halogen with variable intensity.

Simple to use, this microscope empowers you to make an informed decision, quickly without the need for lengthy sampling and costly Lab analysis. Inspired and recommended by popular writer and beekeeper, Randy Oliver, we are delighted to be able to offer this special microscope package as a small contribution towards the challenges facing beekeepers with CCD. Includes microscope, carrying case and slide starter kit. "It is greatly surprising to me that with the great interest by beekeepers in Nosema ceranae, how few actually make the effort to monitor the levels of this parasite in their colonies! Even more surprising is that, despite the considerable expense, many blindly treat their colonies without having any idea as to whether their bees are actually infected!" Randy OliverMicroscope OpticsThe OM36-L includes a binocular or optional trinocular Seidentopf microscope head inclined at an ergonomic 45 degrees. The head rotates 360 degrees for flexible viewing positions and includes two Wide Field WF10x eyepieces and rubber eyecups for improved viewing. The oculars both have diopters that enable individual eye focusing while the head can be adjusted through 55-75mm to adapt for different interpupillary distances.There is a rear facing quadruple nosepiece with four parcentered, coated, parfocal, 185mm achromatic objectives (4x, 10x, 40x spring, 100x spring, oil immersion). Both the 40x and 100x objectives are spring-loaded to mitigate the risk of damage on the slide. Magnification levels include 40x, 100x, 400x and 1,000x unless optional higher power eyepieces are used. A 23mm camera adapter is included with the trinocular version. Tip: Once you have focused the microscope using the 4x and 10x objective lenses, use the 40x objective lens to Nosema Ceranae infections.Stage & FocusThe OM36 series includes an oversize double-layered, graduated mechanical stage that measures 110mm x 120mm. The range of X-Y movement is 70mm x 25mm and the stage includes a spring-loaded slide clamp for exact positioning of the specimen. The stage is controlled by convenient dropdown, coaxial coarse/fine controls so the viewer can operate the stage 'eyes down'. Focusing includes high quality rack and pinion mechanics for longer life and coaxial focus controls for easier focusing. We recommend coaxial coarse/fine focus controls since they enable 'eyes down' focusing. In other words, the viewer does not constantly need to look up in order to find the other focus control. This benefit is important in enhancing a student's experience and therefore in encouraging a more sustained interest in the microscope. Safety features include a rack stop to ensure that the stage does not impact with the objectives and thereby break the slides and a slip clutch control to mitigate the risk of damaging the focus controls through over extension.Condenser & Illumination The condenser is a professional Abbe 1.25 N. A with iris diaphragm for optimal adjustments. Transmitted rechargeable LED illumination includes variable intensity. The LED version requires one 30 minute charge to be used out in the bee yards all day long.Included AccessoriesWe have included a padded nylon carrying case with this microscope to protect it in transit to and from the bee yards. At our request, the case has more padding than competing products. Finally, to get you started, our OMSK-1SP slide starter kit is included. The kit includes 50 blank slides, 100 cover slips, immersion oil, 3 well slides, lens cleaning paper and a pipette - everything you need to start diagnosing yourself!AccessoriesAccessories include Eyecups, Nylon Case, OMSK1SP slide starter kit, Dust Cover, Manual, Spare Bulb, Spare Fuse, Immersion oilRead Randy Oliver's informative article on how to diagnose Nosema Ceranae - Click here Simple Microscopy of Nosema for Beekeepers> weight and dimensions: 16lb. 20"x14"x12"Omano OM36 Series
